Dear Readers, Here we have given the list of important Computer Awareness Glossary, Candidates those who are preparing for the upcoming Banking exams can use this.

COMPUTER AWARENESS DAILY GLOSSARY

Laptop:
Laptop
is a small and lightweight computer in which all the main parts are fitted into
single unit. It is designed to be carried around. Particularly, it is ideal for
travellers, journalists, commentators and professionals who want to work both
at the office and home.

LCD:
Acronym
for “Liquid Crystal Display”. It is the
technology used for displays in notebooks and monitors for computers.

Linux:
An
open source spinoff of the UNIX operating system that runs on a number of
hardware platforms and is made available for free over the Internet.

Log
on & Log off: Each server that is accessed must
have some way to ensure security of their sensitive information. Thus, servers
restrict access by forcing users to “log on” with either personal access codes or anonymously. Anonymous access
usually requires the individual’s e-mail address, and
the user’s IP address is also logged. Once the desired
information has been obtained, the user can “log off”, disconnecting access to the server.

Large
scale integration: A classification of ICs [chips]
based on their size as expressed by the number of circuits or logic gates they
contain. An LSI IC contains 3,000 to 100,000 transistors.

Latency:
The
time interval between the instant at which a CPU’s
instruction control unit initiates a call for data and the instant at which the
actual transfer of the data starts.

Monitor:
The
high-resolution TV-like device that displays your computer’s output. Today’s monitors have much better
quality displays than any TV is capable of producing.

Motherboard:
is
the core of a computer system. It is the circuit board where all other parts
connect. It

communicates
and controls the overall system. No motherboard means no computer system.

MP3:
This
stands for “MPEG I Audio Layer- 3” and is a digital.
compressed music file (their file names always end with an mp3 extension). MP3
files are often downloaded or exchanged between people online.

MPEG:
Acronym
for “Motion Picture Experts Group” A video file
compression system which is used on the web.

Multitasking:
The
concurrent execution of more than one program at a time.

Macro:
In
software engineering, a predefined sequence of computer instructions that is
inserted into a program, usually during assembly or compilation, at each place
that its corresponding acroinstruction appears in the program.

Mainframe:
Term
used to describe a large computer.

Mean
time between failures [MTBF]: A measure of the
reliability of a computer system, equal to average operating time of equipment
between failures, as calculated on a statistical basis from the known failure
rates of various components of the system.

Medium
scale integration: A classification of ICs [chips]
based on their size as expressed by the number of circuits or logic gates they
contain. An MSI IC contains 100 to 3,000 transistors.

Megahertz
: A
unit of frequency equal to one million cycles per second.

Memory
: Any
device or recording medium into which binary data can be stored and held, and
from which the entire original data can be retrieved. The two types of memory
are main; e.g., ROM, RAM, and auxiliary; e.g., tape, disk. See: storage device.

Metal-oxide
semiconductor: One of two major categories of chip design
[the other is bipolar]. It derives its name from its use of metal, oxide and
semiconductor layers. There are several varieties of MOS technologies including
PMOS, NMOS, CMOS.

Microcomputer:
A
term used to describe a small computer.

Minicomputer:
A
term used to describe a medium sized computer.

Mnemonic:
A
symbol chosen to assist human memory and understanding.

Modem:
A
functional unit that modulates and demodulates signals. One of the functions of
a modem is to enable digital data to be transmitted over analog transmission
facilities. The term is a contraction of modulatordemodulator.

Modulation:
Converting
signals from a binary-digit pattern [pulse form] to a continuous wave form
[analog]. Contrast with demodulation.

Multiplexer:
A
device which takes information from any of several sources and places it on a
single line or sends it to a single destination.

World Bank:
President : Jim Yong Kim
Headquarters: Washington, D.C., United States
World Bank Group:
World Bank Group has five international organizations:
♦ International Bank for Reconstruction and Development (IBRD)
♦ International Development Association (IDA)
♦ International Finance Corporation (IFC)
♦ Multilateral Investment Guarantee Agency (MIGA)
♦ International Centre for Settlement of Investment Disputes (ICSID)
